Figure 13 is the cut-open view of the projected position adjusting gear 4 of the installment state representing rail plate 8C.

Specifically, as shown in figure 13, form the interior rail 82 of rail plate 8C under the state abutted with the installation portion 7131 (guide rails assembling portion) caved in the direction contrary with Y-direction of light incident side parts 71 by bearing surface 82A, the screw S1 being inserted through this interior rail 82 fixes.

In addition, the outer rail 81 forming rail plate 8C is fixed on the fixed part PL1 of the tabular body PL of the installation portion 631 of the concavity by screw S2, a part being fixed on the first moving-member 6 by screw S3.That is, the face that the bearing surface 81A of this outer rail 81 is opposed with this junction 81A same of fixed part PL1 abuts.

Herein, the bearing surface 81A that the bottom surface 631A (face fixing for fixed part PL1 of this installation portion 631) of the installation portion 631 of concavity is formed as the outer rail 81 fixed with the tabular body PL being installed in this installation portion 631 becomes coplanar as much as possible.That is, bottom surface 631A is formed as becoming same plane with this bearing surface 81A.Therefore, the size be installed between the tabular body PL of bottom surface 631A and this junction 81A diminishes as much as possible.Thus, suppress the pulling force of tabular body PL to outer rail 81 excessive.

Such pass ties up in the bearing surface 81A of the bottom surface of installation portion 5111 and the bearing surface 81A of rail plate 8A, the bottom surface of installation portion 5121 and the bearing surface 81A of rail plate 8B and the bottom surface of installation portion 641 and rail plate 8D also identical.

In addition, tabular body PL is relative to the direction opposed with the outer rail 81 fixed by this tabular body PL, and the thickness direction namely with the rail plate 8 of this outer rail 81 has spring performance.In other words, tabular body PL is formed by the material that Young modulus is higher than the material forming the parts (support unit 5 and the first moving-member 6) installed for this tabular body PL.In addition, in the present embodiment, tabular body PL is formed by stainless steel, and support unit 5 and the second moving-member 7 are formed by aluminium alloy, and the first moving-member 6 is formed by magnesium alloy.But be not limited to these, material also can suitably be selected and change.

Such tabular body PL plays rigidity relative to the long load along this thickness direction, plays spring performance (elasticity) relative to the load of the moment along this thickness direction.Namely, tabular body PL has following characteristic, namely be difficult to distortion when applying the long load along above-mentioned thickness direction relative to this tabular body PL, some distortion occur a little when applying the load along the moment of above-mentioned thickness direction but original shape can be returned.

Therefore, even if put on projected position adjusting gear 4 in the impact to fall etc., and make outer rail 81 along relative to tabular body PL near and be separated direction instantaneously movement when, this tabular body PL is out of shape, and follow the movement of this outer rail 81, thus also can suppress the stripping of this outer rail 81 and interior rail 82.

Projector 1 involved by the present embodiment be more than illustrated has following effect.

The thickness direction (above-mentioned T direction) that rail plate 8 as guide member is configured to this rail plate 8 is along the direction of the orthogonality of center shaft with projecting optical device 36 that is X-direction and Y-direction.Now, in rail plate 8A, 8B, interior rail 82 (the first guide rail) is fixed on the first moving-member 6 to make the bearing surface 82A orthogonal with above-mentioned thickness direction with the mode that the first moving-member 6 is opposed, and outer rail 81 (the second guide rail) is fixed on to make the bearing surface 81A orthogonal with this thickness direction the tabular body PL being installed on support unit 5 with the mode that the tabular body PL of support unit 5 is opposed.In addition, in rail plate 8C, 8D, interior rail 82 is fixed on the second moving-member 7 to make bearing surface 82A with the mode that the second moving-member 7 is opposed, and outer rail 81 is fixed on the mode that the tabular body PL being installed on the first moving-member 6 is opposed the tabular body PL being installed on the first moving-member 6 to make bearing surface 81A.

Accordingly, even if when the impact because to fall etc. is applied with the stress in the direction that support unit 5, first moving-member 6 and the second moving-member 7 are separated respectively along the central shaft of projecting optical device 36, outer rail 81 and interior rail 82 also can be suppressed to peel off.In addition, and being configured to bearing surface 81A, 82A when observing along the central shaft of projecting optical device 36 and the orthogonal situation of this central shaft (that is, Z-direction) is compared, the size from this central shaft to the outboard end of rail plate 8 can be reduced.Therefore, it is possible to make projected position adjusting gear 4 miniaturization.

In addition, even if when the gauge of rail plate 8 produces deviation because of foozle etc., the outer rail 81 of each rail plate 8 being fixed on the tabular body PL being installed on support unit 5 and the first moving-member 6, therefore also can absorbing the deviation of this gauge when being fixed on this tabular body PL.Accordingly, do not need the rail plate 8 of the size selecting the position being suitable for being set up, in addition, do not need the foozle of so strictly management component.Therefore, it is possible to improve the yield rate of the parts forming projected position adjusting gear 4, and then the yield rate of projected position adjusting gear 4 can be improved, thus can manufacturing cost be reduced.

Be installed on support unit 5 and the first moving-member 6 and the tabular body PL of fixing outer rail 81 has spring performance at the thickness direction of rail plate 8.Accordingly, even if make outer rail 81 along when moving relative to interior rail 82 direction that is close and that be separated when being applied with above-mentioned impact, tabular body PL is also to be out of shape with the mode of keeping strokes of this outer rail 81, thus the stripping of interior rail 82 and outer rail 81 can be suppressed, and then the generation of stripping of support unit 5, first moving-member 6 and the second moving-member 7 can be suppressed.Therefore, it is possible to stably keep projecting optical device 36.

Herein, when bottom surface 631A and the bearing surface 81A of the outer rail 81 fixed by this tabular body PL of the installation portion 631 of the part configuration for tabular body PL are roughly not coplanar, the size between this bearing surface 81A and tabular body PL becomes large.In this case, the pulling force acting on the tabular body PL of outer rail 81 becomes large, and when being applied with the impact falling and wait, outer rail 81 becomes greatly along the load in the direction be separated from interior rail 82.

On the other hand, bottom surface 631A and bearing surface 81A is roughly coplanar, can reduce the size between this junction 81A and tabular body PL thus.Therefore, the above-mentioned pulling force of tabular body PL can be reduced, even if when applying the impact to fall etc., outer rail 81 also can be suppressed from the stripping of interior rail 82, and then the generation of stripping of support unit 5, first moving-member 6 and the second moving-member 7 can be suppressed.Therefore, it is possible to stably keep projecting optical device 36.

In addition, the bottom surface of other installation portion 5111,5121,641 also becomes roughly coplanar, thereby, it is possible to play effect same as described above with the bearing surface 81A of the outer rail 81 being fixed on the tabular body PL being installed on these installation portions 5111,5121,641.

The light incident side parts 71 of the second moving-member 7 have the installation portion 7131 as guide rails assembling portion caved in the inside, are configured with rail 82 in rail plate 8C in this installation portion 7131.Accordingly, the size from the central shaft of projecting optical device 36 to interior rail 82 can be reduced further.Therefore, it is possible to realize the miniaturization of projected position adjusting gear 4 and then projector 1.
